Etymology

The three letter root (ف ص ل) gives the meaning of distinguishing one thing from another, as well as separating it from something else. From this root comes the name FaySal, which means a judge. From this root comes the word “mifSal” which is a name for the tongue (in that through its use speech is distinguished) and is also the word for a joint. [ibn fa_ris, Maq_yi_s al-Lugha]
